INl'PROVEMENT IN PAPER OLLAR MACHINES.

Specification forming part of Letters Patent No. 165,803, datsd J uly 20, 1875 application filed January 11, 1875.

from a continuoussheet or strip of collar-stock dplex collar-blanks, each comprising two prints of collars, which lap by each other endwisehalf their length, or thereabout; and to this end 1n-y invention consists, principally, of

certain combinations oi' embossingdies, a supporting bed,"feeding mechanism, and cutting mechanism, which are specified in detail at the close of this specification; and by whole action the'sheet of paper-stock ismoved between embossiH-g-dies, which lap by each other longitudinally for half their length, or thereabout, and which indent it as required for the finished collar and is then transferred lengthwise of the dies to the cutting mechanism, by means ofi which the embossed blanks are eut from the sheet, so that the ncessity of taking the Stock out of one machine and of entering it V irito another is dispensed With.

In-0rder that the invention may be fully understood, I have represented in.the accompanymg drawings, and will proceed to describe,

a collar-blank machine in which all my said improvements are embodied in the best form which I have thus far devised.

Figure 1 represents a front view of the said Fig. 2 represents a plan of it with moved. Fig. 4 represents a plan of the platen reversed, with the embossing-dies. Fig. 5 represents the blank Severed and embossed.

The embossing-dies F F in said machine are constructed with edges adapted to indent the paper. so as to produce the appearance of stitch- 1ng, and also With an edge t0 crease t at the hne of gunction of the collar and the collarband., They may also be fitted with other edges for creasing the stock at other places.

These dies are secured t0 a platen, E, in such manner-that each die' (as represented in the drawmg) laps by the other fol hait its length.

The platen is caused to rise and descend by means of two revolving eccentrics, R B, that porting-bed, N, the surface of which should be faced With a sheet, 0, et hard pasteboard. This bed N is secured to the platform B of the machine, and the paper, while passing ove r it. is guided length wise of the dies b edge-gmdes on, two arranged at each end of the bed. In order that the button-holes for the stud and back button may 136 ont simultaneously with the embossing,'l combine button-hole cutters 1 with the embossingdies, and cause both to be operated by the platen E. For this purpose the bar or shaft of each button-hole cutter is arran ged t0 slide vertically in a suitable guide,

D, and is provided with an jarm, which projects into a slot, 3, formed in the edge of the platen, so that'when the latter m'oves down and upit forces the button-hole cutter down through the collanstock and mises it atterward; or the arm of each button-hole cutter may project under the edge of the platen, and be caused to rise with it by means of a spring, which I prefer to arrange in a cavity of the guide. 1 prefer to construct the operating end of each button-hole cutter as a punch, and to maire a hole in the snworting-bed to act as a die, so that a narrow piece is punched out of the collar-stock in forming the buttonhole.

The cutting mechanism for separating the embossed collar-blanks from the sheet consists of a fixed shear-blade, J, and of a reciprocating shear-blade, f,,which shear the stock. The edges of these two shearblades have a 2 form, as represented in the drawings, so that the eut made by them corresponds with the line of division between the adjacent ends and cdges of the blanks when ont ont so as to lap by each other endwise. This cutting mechanism is arranged beyond the ends of the embossing-dies, and the distance of the sheanblades from the embossing-dies is a multiple of the length of a collar-blank, so that whenthe shear-bladcs and embossingdies opcrat simnltaneously the former will sever the sheetat the correct dividingline between successive printS of the embossingdies. The ,shear-blades are combined With the embossing-dies by the frame ot the machine, and through the intervention of the rock-shait I, the amfn U, the connecting-rod V, the crank-pin t, the driving-shaft S, and the platen E; but as the pecnliarities of this combining mechanism' constitute no part of the inventionit may be varied as circumstances or the peculiar views of different users may render expedieiit. The embossed sheet is held in place edgewise during cutting by means of edgerndes 2'. The feeding mechanism, by means of Which the stock is moved through the machine lengthwise of the emlmssing-dies, is arranged between the embossing-dies on the one side and the cuttin g mechanism on the other. It is Composed, in this example, of a pair of feeding-rollcrs, H H, one of which is arranged beneath:the level of the face of the supporting-bed N, and the other above it. The journals of each roller :are fitted to revolve in.suitable boxes connected With the frame of the machine, and the boxes 'of the upper roll have set-screws applied to them, so as to regulate the gripe of the rollers upon the sheet passing between them. The rollers are cansed to move the stock, whenthe embossing-dies and movable shear-blades have risen from the stock, and before their descent, by connecting the feedrollers with the driving-shaft by means 01 the toothed segment W, the wheels g g and the shaft X. As the toothed segment W is used the feedrolls are operated intermittently during the periods when the ter :h of the segment Ware driving ehe wlieei 9. In the in tervals between these periods the feed-rolls resta. Thefeeding mechanism may be greatly varied, as found expedient.

4 When the machine is to be put in operation a sheet of paper wide enongh t0 foim two rows of collars whose members interlock sidewise, but lap by each other endwise, as represented in Figs. 2 and 5, is introduced at the opening in the standard A, and is pushed along the bed of the machine until it is nipped between the. feed-rolls H. The machine is then set at work, and the paper is embossed by the dies and moved through the machine, lengthwise of' the embossing-dies,

' over the supporting-bed at intervals. As soon p1ints of two collars, as represcnted at Fig.

5; and this shearing is efiected simultane- 'ously with the indenting of the new prints by the embossing-dies upon the extension of the sheet moved into the machine. The buttonhole cutters, when used, operate simultaneonsly With the embossing-dies.

I do not claim the members of my machine separately. Neither do I claim broadly to be the first who combined, in one machine, embossing-dies, feeding mechanism, and cutting mechanism. N or do I claim any feeding mechanism combined with lengtlnvise-cutting dies, which eut out one or more perfect collars from a strip, as shown in patents granted to Gr. K. Snow, October 29, 1872, whether said cuttingdies lap by each other or not; neither do I claim any part of these; but

What I claim as my invention is 1. The combination and arrangement, substantially as hefore set forth, of the two collanembossing dies, arranged t0 lap by each other longitudinally, the supporting-bed, the cutting mechanism, and the feed mechanisxn, located between the said dies and cutting mechanism, whereby t-I web is drawn past and from said dies, and advanced to the cutting mechanism, by Which pieces are severed from the web by acombined longitudinal and transverse eut, having .npon each piece two 01 more collars embossed.

2. The combination and arrangement, substantially as before set forth, of the two collar-embossing dies, arranged' t0 lap by each other longitudinally, the supporting-bed, the button-hole cutter, the cutting mechanism, and the feed mechanism, arranged betwccn the. said dies and cntting meclmnism, whereby the web is drawn past and from the said diesand buttoi1-hole cutters, advanced to the cutting mechanism, and pieces of paper sevred from the web by a combined longitudinal and transverse eut, each piecc having two or more collars embossed thereon and the button-holes ont.
